, To all 'whom it may concern:

Be it known that I, HENRY C. Hnnn, a citizen of the United Statesof America, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have inventedcertain new and useful Improvements in Machines for Applying Chine- Hoops to Cylindrical Bodies, of which the following is a specification, reference being had therein to the accompanying drawings. The invention relates to the manufacture of barrels and similar packages, and has more particular reference to mechanism for applying chine-hoops thereto- As specifically shown, the machine isadapted for the application of such hoops to cylindrical bodies formed of paper or fibrous material, and it is the object of the invention to apply a hoop that will reinforce and strengthen the chine and alsowill bind the edge and form an inner seat for the reception of the head. l V I The invention'comprises, first, means for positioning the hoops upon-the chine; further, means for contracting and tightening said hoops upon the body; and further, various features of construction as hereinafter set forth.

In the drawings: I

Figure 1 is a side elevation of the machine;

Figs. 2 and 3 are elevations at opposite ends of the machine;

Fig. 4 is a cross section showing in elevation the hoop-contracting mechanism;

Fig. 5 is a longitudinalsection onlin Fig. 6 is a central section through one of the eccentric bushings;

Fig. 7 is a sectional view of the hoop and the body to which the hoop is to be secured before the machine has operated;

Fig. 8 is a sectional view of the hoop and the body to which the hoop is secured after the machine has operated.

1 is a suitable bed or frame'upon opposite ends of which are vertical extensions 2 and 3 carrying the hoop-applying mechanismfor opposite ends of the barrel, sufficient clearance being provided between these extensions for receiving the barrel body.-

These mechanisms at opposite ends of the machine are in many respects exact duplicates, but provision is made for a relative movement longitudinally of the bed, which necessitates the mounting of one of the mechanisms on a traveling head, whereas the other may remain in fixed position. Each of these duplicate mechanisms comprises a head 4, which has a portion adapted to fit within the end of the cylindrical body,-

and an annular shoulder portion 5 for bear ing against the end ofthe chine-hoop and pressing it into full engagement with the body. The heads 4 are mounted upon rotary shafts 6 and 6 which, in the operation of the machine, are revolved in unison through the medium of mechanism of the following construction:

7 is a shaft'extending longitudinally and centrally of the bed 1 and j ournaled in suitable bearings therein. 8 and 9 are gearwheels upon opposite end portions of this shaft, and which respectively engage pinions 10 and 11 upon the shafts 6 and 6?. As these intermeshing gear-wheels and pinions are in the same ratio, it is obvious that the shafts 6 and 6 will revolve in unison.

Adjacent to each of the heads 4 is a non- V movement to all of the arms 13, which will I cause the rollers 14 to move toward or from the periphery of the rotary heads 4. In addition tovthe rock-arms 13 there is provided arock-arm 18, which carries a roll 19 having perforating punches 20 in the -periphery thereof. This rock-arm 18 is mounted on a rock-shaft 21 journaled in-the head 12, at the opposite end of which is a rockarm 22 having at its free end a roll 23 engaging a cam groove in a gear-wheel 24,

which is driven from a pinion upon the shaft 6. The Wheel 2i is also provided with a second cam, preferably on the opposite side thereof, vvhich engages a roclnarm connected with a gear-segment- 2'? which ena gear-segment in the periphery of the ring 16. Thus during the rotation of the shaft 6 and head i, movement is communicated to the cam Wheel 2% by the lPlIllOIl 25, Which causes the rocking of the arms 13 and 18, as will be more fully hereinafter described The rock-arms 13 and 18 are normally under tension ct-springs 13 and 18 which springs are anchored upon the head lfl and tendto move said arms toward adjustable stops 13 and 18 As thus far described, the mechanisms upon opposite ends of the machine are duplicates, but, as previously stated, one of these mechanisms is mounted upona slide movable longitudinally of the bed; As shown in l, the mechanism on the lefthand'end is mounted upon a slide 29'engaging suitable slideways in the outward extension 2 of the frame; This slide is actuated by a cam 30, preferably formed integral with thegear-Wheel 8, andvvhiclr engagesa'roll 31 CODDGClLGClWlill the slide A yielding connection is preferably provided between theroll an'd'the slide, comprising a slicing block 32 to ivhich'the roll is directly attached, which block recessed to receive a spring 32%"engaging a bcarii 3-l at the end ofthe shai't The sliding bloci-z has an aperture therein through which the reduced end oi shaft 6 reciprocates. A set-screw 35, secared'to the vertical extension 2, bearing against the op posite end of the bloolrilil serves to adjustably limit the movement.

The construction just described is such that the rotation of the cam 30 ivill'impart a l'GClPI'OCfllOly movement to the slide 29, and as all or" the mechanism surrounding the heads is mounted upon this slide, it will move unit along the' bed 1'; 'lh's' movement does-not interfere vvith the trans mission oirotai'y movement to the shaft 6, as the pinion 10' is of sufficient length to remain in mesh With'the gear-WheelS during thismovement. The gear-Wheel 8 driven from a suitable I drive pulley- 36 sleeved upon the end of ClS shaft and turning t'reelyi thereon, through the medium of an intermediate transmission, including a pinion 37 connected with the'pulley a clutch-Wheel 38 driven from said })il1iOiI, a shaft'39driven from the clutch-uh and a pinion d0 on said shaft meshing-v th the gear-wheelS. T he clutch-Wheel 38 con tains a suitabletrip-mechanism 38 of any Well known type (not shoivn in detail) V "WlllClYlS controlled by a hand-lever-lhand which is adapted upon the actuation oi said lever to communicate motion ctromthe Wheel 38 to the shaft 39, and continue it through one complete revolution, after which further movement is arrested.

For engaging and disengaging the cylindrical body upon the bedor frame, there are mounted upon the bed'l inclined crosstracks 4:2 and adjacent to these tracks are ro'cl-:arms d3 connected by an intermediate lever system with a controlling lever at. These rock-arms 43 act as stops in certain positions, they being so arranged that in connection with the inclined tracks l2- they will normall serve'to support a cylindrical barrel body upon the bed, in substantially axial alinement \vith'the 'h'eads l, but 111 a movement of the-lever l -l thea'ochar-ms are depressed to release said body and permit it to roll off of the inclined tracks; a

in the operation ofthe machine the cylindr-ical-bodies to which thechinedi'oops are to cc-applied, are successivelytedupon the'inclined tracks i2 and' will automatically assume a position in substantial alin'ement with the heads 4 The-lever ell is then operated to trip the clutch mechanism and colinunicate motion from the drivepulley 36 "the shaft 89, andthrough the pinion d0 to'the gear-Wheel 8. This gear vvheel be ing in mesh with the pinionltl'will drive thelatter, While an exactly corresponding movement is transmitted to the pinion 11' throu 'h the shaft 7 and gear-Wheel 9. Be- 7 ng fed up'onthe machine, thebarrel the chine hoops for the opposite ends thereof loosely placed in position. These hoops will therefore be concentrically arranged in relation to th'eheadsl and When the head on the left-hand end of-the machine, l 1, is moved-toward the opposite head said hoops Willmount up on the heads "105 a, the inner ends of whichare-tapered. This movement of the left-hand head is efiect'ed. as above described, by the camfidimparting movement to the roll 31 on the slide 32, and through the yielding spring 33 transmitting movement to the slide 29. "She"amountoi movement suliicient to completely force the hoops upon the ends of the body, and any slight variation'in thelehgth of said bodies ulll'be ta lren care ofby the yielding of the spring 38.

After the hoops are thus fully engaged with the cylindrical bodyjthe further ro my movement of the heads sand the corresponsling movement of the cams 28-"and Will cause a rocking of tlrearmsQQ and The latter-Will actuate the gear-segment 27, which is'in meshivith the gear-segment 28 on the ring 16, imparting a rbtary'mo vement' to the lattenvrhich, through the eno'agement of the pins with the slide bearngs 7.7 in the rock-arms 13, will cause a simultaneous and equal rocking movement of all of saidarms. This will carry the rolls le inward causing them to bearagainst the 130 chine-hoop and rolling the outer part ofgg ilongitudinally of said bed, mechanism for same so as to cause a contraction in diameterf? borrespondingly driving said duplicate mechand a forcing inward into firm contact with? anisms, permitting of the movement of said the cylindrical body. The rock-arm 22 willl carriage, and means for moving said carcause the inward rocking of the arm 18,? flriagetimed with the movement of said dupli+ which carries the punch wheel 19, and the icate mechanisms to cause a sequence of oplatter during the rotation of the head willi erations; substantially as shown and for the form a row of perforations or indentations] in the chine-hoop which will assist in 0011-; tracting the same and in securing it to the body. The inward movement of the rolls 14 and 19 is assisted by the springs 13 and 18 while the stops 13 and 18 will limit} the inward movement. The timing is suchl that only one complete revolution of the, the punch roll 19 is Ii At the completion of the operation abovej described the chine-hoops on both ends ofi head is performed While in operation.

the barrel will have been rolled and co tracted in diameter to firmly attach the sam to the barrel body. The cam 30 has no however, completed its movement and durmg the remaining portion of the cycle Wlllj operate to withdraw the slide 29, separating the heads 4 and withdrawing the same from engagement with the chine-hoops and the cylindrical body to which they have been applied. This permits the barrel to rest upon the inclined tracks 4-2 and rock-arms 43, but when the operator actuates the lever ad, the rock-arms a3 will be withdrawn permitting the barrel to roll oif from the inclined tracks.

In applying hoops to bodies formed of different gages of stock their outside diameter must be varied. This requires an adj ustment in the hoop-contracting mechanism which I have provided for as follows: The rock-arms 13 are pivoted upon studs 45, which, as shown in Fig. 6, engage eccentric bushings 46 in the head 12. These bushings are provided with gear-teeth engaging adjustable screws 47 in the head 12, operable from the periphery thereof. This permits of rotating the eccentric bushing so as to move the studs 45 inward or outward, which will compensate for variations in thickness of the stock. When adjusted the studs 45 are clamped in position by nuts 48 engaging threaded portions d9 thereof.

To protect the mechanism surrounding the heads an annular shield 50 is preferably placed thereabout, as shown.
